Answer:
B. Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down.
Explanation:
The options D and A can be eliminated because when a gas expands without gaining additional mass, it will become less dense; when a gas contracts without losing mass, it becomes more dense. Therefore, these two options conflict with the idea of density and cannot be true.
Option B is superior to Option C because convection currents are typically portrayed as beginning with the rise of warm air, which displaces/is replaced by cooler, dense air from the upper atmosphere. While Option C is similar, it describes the opposite series of events.

Answer:
The correct answer is (a). The brown beetle migrated to island #1 and gave rise to the colored species on island #2 through adaptive radiation.
Explanation:
As there are no brown beetles on the island 1, and island 2 has less biodiversity of plants, it's possible to think that the brown beetle migrated to island 1 where there are many kinds of different plants, which would lead to the adaptation of these organisms resulting in many different species.
Answer: protein
Explanation:The product of RNA translation would be proteins. This process is a part of gene expression. The RNA in translation process is decoded outside the nucleus and produces an amino acid chain or a protein. Hope this answers the question.
